EBP developed and maintains a web-based IT system for the Federal Highway Research Institute (BASt) for planning, evaluating, and coordinating work and bottlenecks on the German federal highway network.

In Germany, responsibility for planning and implementing roadworks on federal motorways has been transferred from the federal states to the federal government's Autobahn GmbH. When planning roadworks, it is becoming increasingly important to assess their impact on traffic flow and numerous other factors. The federal states and Autobahn GmbH act independently in this regard and pursue different approaches to assessing their roadworks. However, they are required to report some of these roadworks on federal highways that are expected to have a significant impact on traffic to the Federal Ministry of Digital and Transport (BMDV) for further review. Before the project began, this process was only partially automated. As a result, it has not been possible to carry out a complete and timely review of possible interactions between work sites across the entire federal motorway network, nor has it been possible to reuse the analysis results.

The BMDV has therefore commissioned the Federal Highway Research Institute (BASt) to introduce a nationwide, IT-supported traffic analysis system (VAS). EBP was commissioned by BASt to develop this new system. It should enable the federal states and Autobahn GmbH to record work sites directly via a browser-based GUI or to transfer them to the VAS via interfaces using their own systems. Work sites can then be checked in the VAS using a modular evaluation procedure and, if necessary, submitted to the BMDV. Evaluation results can also be transferred from the VAS back to regional systems.

The assessment includes an analysis of congestion-related time losses using a deterministic queueing model, emissions, traffic safety aspects, economic costs, and a rule-based evaluation based on various criteria. To enable forecasts, data from permanent counting stations on federal highways is used and various parameterizable models are supported. Data from the “Bundesinformationssystem Straße” (BISStra) geoinformation system is also used to establish the necessary spatial references. This information is also used in the modern web client to enable visually appealing map displays.

In addition to the assessment, the VAS also maps processes relating to construction operation planning and reports to the federal construction site information system. For this purpose, construction site data is exchanged bidirectionally with the MDM platform (MDM - Mobility Data Marketplace), among other things.

From the outset, the VAS has been designed to comply with and continuously monitor high standards of IT security and data protection, especially for web applications in cloud environments. This applies to both the various web interfaces for different user roles and the standardized web services for authorized interface partners. As the traffic analysis system is expected to be used more and more intensively in the coming years, resulting in a sharp increase in the amount of data to be processed, the system has been designed for scalability from the outset. In addition, the clearly structured internal architecture allows future functional enhancements to be easily integrated. This means that it is also optimally prepared for the requirements of the future.
